Here is a pinout for making a cable to connect an M8027 module to a standard
Centronics 36 pin connector.  We have used this cable on many of our in-house
RT-11 systems and Epson-style printers.

In addition to being a DEC dealer, we are a hobbyist in the areas of RT-11,
OpenVMS, Oregon Software Pascal-2.

Thanks.
